Similar Species: May have subspecies. Seal Salamanders, Desmognathus monticola, typically have heavy black or dark brown spots on their backs and are larger as adults than this species. Mole Salamanders, Ambystoma talpoideum, are distinguished by their lack of nasolabial grooves. Plethodon species do not have a light line from the eye to the angle of the jaw, their hind and front legs are about the same size, and their body form is long and slender.
Reproduction: Breeds June to September.
Habitat: Prefers mucky or rock-strewn areas along woodland creeks, seepages, springs, floodplains, upland streams etc.
Behavior: This species can shed its tail as a defense against predation. It lacks chemical defenses, but may try to flee or bite to deter predation. Typically more active at night. During warmer months may be seen on the ground near sources of moisture. Moves underground into burrows or hidden retreats during colder times.
